How to get my pygmy cories to at least lay eggs

[aqua hero]

Hi, so I have had my pygmies for a couple of months now, I would say I have around 9-10 left. Alot of people said online that they can easily lay eggs by just doing water changes.

Months have passed and I haven't seen them lay any eggs. I have done 50 % water changes weekly, bi weekly, monthly. Nothing.

Should I try adding blackwater extract to help stimulate breeding? People say it has helped

My Tank is planted well and has sand in it as well. The temperature is around 25c. I feed sinking pellets, daphnia, Brine shrimp, white mosquito larvae and bloodworms.

I would like to know trick to get them to lay eggs.

Try not doing a water change for a month and then do 50-75% water change with rather cool water (like 21-22c) seems to be the magical formula as well as minimizing disturbances. most breeding articles on corys state that as sonn as the keeper gave up and stopped checking them regularly they spawned. If you click this

Corydoras pygmaeus

it will take you a page of all listed keepers and most of what we know about that species, furthermore you can even check others breeding reports near the bottom.

this would also make a good read ;)

I'm in the process of setting up a primarily invert tank, but wanted to have some fish in the tank to go with them. I picked up 24 pygmy corries the other day and added them to my 160G planted tank.

If I notice any breeding behavior I'll be sure to post back here on what route seemed to do the trick.
